Question 773475
Dividend = Quotient * Divisor + Remainder
Here Dividend = 67 - 2x
     Divisor = x
     Quotient = 14
     Remainder = 3
So   67 - 2x = 14x + 3
or   14x + 2x = 67 - 3
or 16x = 64
or x = 4.

check: Dividend = 67 -2x = 67 - 2 * 4 = 67 - 8 = 59
        59/4 = 14(quotient) with remainder 3
